R&B star Chris Brown has filmed a drunken taxicab confession-style video and opened up about falling in love with Karrueche Tran when he still had feelings for Rihanna.

The footage was released on Vimeo.com just hours after Brown confirmed on Thursday he had split from Tran so that he can continue rebuilding his friendship with Rihanna.

The video, shot in the back of a cab, begins with Brown admitting he feels tipsy after partying, before talking candidly about having feelings for two women - as clips of both Tran and Rihanna appear.

He says, "We had fun at the club. I'm a little drunk so I'm gonna be honest. Y'all don't really get the real Chris Brown, so I'd like to just be honest, man. I'm stressed out... it ain't about the music - I love my fans.

"It's just, you know, when you share history with somebody then you tend to fall in love with somebody else, it's kinda difficult. It's like, is there such thing as loving two people? I don't know if that's possible, but for me, I just feel like that. Y'all are probably like what the f**k is he talking about right now? But I'm being real. I don't wanna hurt either or (sic). I'm just me - I'm not trying to be a player, my mama raised me differently. So it's like, I just can't, (it's) too much... Life of Chris Brown."

Rumours of a possible romantic reconciliation between Brown and Rihanna have prompted angry criticism from her fans, but she has apparently hit back by tweeting, "Ain't nobody bidness (sic)... But mine and my baby!"

Meanwhile, Tran appears to have been left heartbroken by the break-up - she tweeted, "All I'm saying is... You don't mess with people's genuine feelings. You just don't!"

Brown split from the Umbrella hitmaker in 2009 after he infamously left her battered and bruised during an argument on the eve of the Grammy Awards.
